Beit knownthat We, Vzuciiaon` C. Einer@ soNa'nd HORACE' L. CONRAD, citizenszof the United Statesfresiding at; Seattle, inf the county of' King and StateotlVashington,

liave Yinvented' a certain new and usefullin-V provement in Vheel vlP-ullers, of which lthe following isa specification:

Our invention` relatesV to improvementsin Wheel pullers and morep'articularly to4 the typeot Wheel'pullers adapted' I"or-remov Ying' rear Wheels-v otautomotive vehicles or for: removing* gears or the like from; their associated shafts' or spindles and theobject of our invention is to provide a Wheelpullcr embodying novel axiallyA and radially adjustable anti-spreading mechanism Where- "by the grippingarms oiiisaidpuller are retained in a predetermined or fixed position against outward movement rinotherobject` is to providea Wheel pullerlaving means 'u'ponthe outer ends of the lgrippingarms thereof whereby the associated spoke engaging` plates areseated and retained in operativeV position' upon the Wheelto'be removed during `the removing operation, j j A With the above and other more speciiic Vobjects in view" which' will appear asthe de- 'scription proceeds, our'invention resides in the novel construction, combinatiom-adaptation and arrangement i of p arts: hereinafter describedand claimed.

7e accomplish these objects by devices illustrated in the accompanying drawings, Wherein- Figure 1 is a. vievv in end elevation oi?" a Wheel puller' embodying the features of'your Vinvention and as-it Wouldappear Whenfoperatively disposedupon the rear Wheel of an a utomotive vehicle;

Fig. 3 is a perspectiveview offthe grip-- Referring to the drawings throughout which like reference numerals designate like parts, the numeral 10 designatesfa rear Wheel of an automotive vehicle and 11` a .vheel puller embodying our invention and illustrated asoperatively disposed upon said Wheel.

.The Wheel pullerll comprises a spindle 12,` an actuating handle 13T, altravelling nut or crosshead `111,. grippingA arms 15, spoke engaging plates 1G and'axiallyand radially adjustable antisspre-ading mechanismv 17'Y for `the gripping arms 15.

- rll-he'spindle 12 isscreiv 'threaded throughout the length thereofI` substantially 'as shown, and is adaptedjto receive' upon the outer end thereoii the actuating handle 13,`

which handle is adapted" to be iixedlysecured in` perpendicular relation. thereon in any Well known manner. Y

The travelling nut 14 is adapted4 to be threadablv engaged forV axial adjustment upon the'spindie 12, and is provided with a 'plurality of integral outwardlyA projecting radial arms`18, Which arms areiormed substantially in `the shape andfmannerI shown in Figs. 1, 2 and 5, each of 'said' arms being provided withal plurality' ofspaced or equidistantv holes orapertures 19 adjacent the inner edges thereof and iii-aligned parallel relation thereto.

Vwhich claw members arel provided on their inner :tacesthereof with recesses 22, which recesses are adapted to normallyreceive the spoke engaging plates lduring the opera- 4tion of removing a wheel or the like, as

more clearly shown in Fig. 12, to thus pre# `vent1 the dislodginentv of said plates during the Vsaid loperatipn. Y

VFormed vvithin'the' inner endportions of the gripping :arms 15 are Vlongitudinally and mediallydisposedfslotsf23, which slots are also disposed in aligned relation with re- `spect to the bifurcated inner ends of said gripping arms.

Formed within the outer edges of the walls of the longitudinal slots 23 'of the gripping arms 15 are a plurality of arcuate notches or serrations 24, substantially as disclosed in Fig. 3.

The axially and radially adjustable antiV :spreading wmechanism 17 for the gripping The spacing sleeves or washers 27 are adapted to be concentrically disposed for free axial movement upon their associated stems 2t,Y and are provided with semispherical inner ends, which ends are adapted to normally seat in the selected arcuate notches 24 formed in the outer edges of the gripping arms 15.

The adjusting nuts 28 are adapted to be threadably engaged upon their associated stems 26 for axial adjustment thereon, said nuts being adapted to normally abut the outer ends of their associated sleeves 27, to thereby maintain and retain the inner ends of said sleeves in their associated selected notches 24, as will be readily apparent by referring to Fig. 2.

. V,It will be obvious from the foregoing and by referring to the drawings that the bifurcated ends ofthe gripping arms 15 may be adjusted upon the arms 18 of the nut 14 by selecting any of the holes 19 in said arms, also that the angularity of said gripping arms 15 with respect to the axis of the spindle 12 may be regulated by the anti-spreadlng mechanism 17, to thus accommodate wheels or gears of varying sizes.

In the operation of our wheel puller the` i same is disposed upon the wheel 10 by abutgaging plates are then positioned to contact ting the inner end of the spindle 12 against the outer end of the associated rear axle 30 of said wheel, the hub cap of said wheel hav# ing been previously removed, the spoke en with two or'more of the spokes 31 of Said wheel -upon the innergsides' thereof',- asshown. Saidplates are thenengaged by the claw members 21 ofVY the gripping arms 15 in such a manner that the plates 16 willseat within the recesses 22 Vofjsaid claw members.

The anti-.spreading mechanism 17 is then moved inwardly upon the grippingV arms 15 engaged therefrom.

to the desired or selectedYY notches V24e and the inner ends of the sleeves 27are caused to seat within said notches by adjusting the nuts 28 upon the stem26, to thereby pre- Y vent outward movement of said arms and to positively clamp the wheel pullerl11 to the wheel 10.

Thepwheel 10 'is then disengaged'or re' leasedlfrom its associated rear axle 30 by giving the actuating handle 13 a few turns which causes the nut 14; to move outwardly upon its associated spindle 12, whichcou'tward movement of said nut is transmitted to the wheel 10 throughthev gripping arms 15,

.thus causing the said` wheelcto move outwardly upon said rear axle and become dis- To` disengage theV wheel 10,7'the setting of only oneofthe gripping arms 15 need. be disturbed, thus facilitating and eXpediting the Ypositioning ofthe wheel puller 11 upon vvanotherwheel of similar size tobe removed. i

In practiceand after exhaustivertests and experimentationwe have found that a wheel puller fabricated in accordance withV our invention to'be very effective and economical in construction and operation. V

From the foregoing .description'taken in connection with the accompanying drawings, the advantages of construction and the method of operation will be readily apwheel puller*fromV the parent to those skilledfin the art to which g our invention relates, to thus kenable those so skilled to fabricate and operate the same, but, while we have described the principle of 'operation of the invention, together with the device which we now-consider to bevtheAV best embodiment thereof, we desire to have it understood that the wheel puller shown is merely illustrative and that such changes may be madewhen desired as are within the Y scope of the invention and embodied in the y accompanying claims.

What we claim 1s 1. An anti-spreading mechanism for the gripping armsl of a wheel puller comprising a spindle an axially movable collar thread-,;

ably disposed within said spindle, a plurality of radially disposed threaded stems extending outwardly from vsaid collar and adjusting meansthreadably disposed upon said stems adapted to restrainingly engage; 1

said gripping arms againstvoutward move-` ment from a predetermined selectedV posi 2. `An anti-spreading mechanism-for the and notches,v of a wheelpuller comprising a spindle, Van axially movable 'collarV thread! f ablydisposed within .saidj'spindle, "a pluf longitudinally gripping arms of 'Y a wheels puller which ar1i1s` are providedwith slots i rality of radially ldisposed threaded stems extending outwardly from said collar and to pass through the slotsof said gripping arms,

thereby retain said gripping arms against outward movement from a predetermined selected position. 10

In Witness whereof, We hereunto subscribe our names this 23rd day of November A. D. 1921.
